Input Rotational Speed: The input rotational speed from the swing motor (not included) is typically in the range of 1000 - 2000 revolutions per minute (rpm). The gearbox is designed to accept this input speed and convert it into the appropriate output speed for the swing mechanism of the excavator.
Output Rotational Speed: The output rotational speed of the gearbox, which drives the swing of the upper structure, is generally in the range of 20 - 100 rpm. This speed range provides the necessary control and maneuverability for the excavator's swing operation, allowing for both quick repositioning and precise adjustments.
